The patch titled
Subject: ocfs2: clean up redundant NULL check before iput
has been removed from the -mm tree. Its filename was
ocfs2-clean-up-redundant-null-check-before-iput.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Joseph Qi <joseph.qi@xxxxxxxxxx>
Subject: ocfs2: clean up redundant NULL check before iput
Since iput will take care the NULL check itself, NULL check before
calling it is redundant. So clean them up.
